GUI LIN NEW GLORY MACHINERY CO., LTD : principle of turbocharger (6)

The key component of the turbocharger is the bearing. This kind of bearing named according to the lubrication form is called "full floating bearing", the working speed is extremely high, the working environment is bad. Therefore, it is very important to ensure lubrication. If the oil supply is slow due to low oil pressure, the bearing will be damaged and the turbocharger will fail. Such failures do not occur during normal engine startup, but if the engine starts for the first time after oil changes and oil filters, slow oil supply will occur, resulting in a lack of oil lubrication in the bearings. In this case, you should idle for about 3 minutes after starting. You cannot directly increase the speed to the starting speed of the turbocharger. Similarly, after high-speed and uphill also do not make the engine stop immediately, to make the engine continue to idle running for 1 minute or so, so that the turbocharger bearings still continue to idle will not be short of oil. Therefore, the use of turbocharger car drivers, must follow the manufacturer's instructions to operate, but also pay great attention to the quality of the oil, should not be regarded as the turbocharger car general vehicle operation.
